Dew point
Dew point set DS 52 for adsorption dryers
Dew point set DS 52
consisting of:
• Digital process meter DS 52
• Dew point sensor FA 410
• Standard measuring 
• chamber
The measuring range of -80...20 °Ctd makes the dew point set DS 52 with alarm the 
ideal dew point monitor with analogue output 4...20 mA.
The dew point sensor FA 410 is extremely long-term stable and can be installed 
and removed quickly and easily under pressure by means of the screwable measuring 
chamber including quick-coupling. The dew point set is supplied ready for plug-in, 
i. e. everything is completely wired. The alarm values can be freely adjusted.
Description      Order no.
